Image upload lists file name, but doesn't store image

When I attempt to upload an image, it acts as though it has uploaded it, showing the filename with a delete checkbox as expected, but the image preview doesn't show and no file ever actually gets stored on the server. If I submit the node and then going back to the edit screen, the image is no longer listed.

It must be server permission issues. I hope you can provide ssh/remote access and admin login details to check the issue so as to resolve this issue, as it seems this being server issue not drupal issue.
